The excess of the motorbikes is as follows:

up to 100cc -
€300.00
up to 125cc - €500.00
up to 250cc - €700.00
up to 650cc - €800.00
up to 1400cc - €1000.00

Excess means the amount you are liable to pay
if the accident or damage is your fault. The
definition of 'your fault' may not match your
definition or ours. If you are involved in an
accident, even a minor one, try to take photo's or a
video of the circumstances. The probability is that
being a foreigner involved in an accident with a
local, you may find the odds somewhat stacked against
you. Please do not interpret that to mean that the
system is unfair, but you will not understand the
language or the nuances of the way things are
presented, which is a difficult enough thing to deal
with when you are in a mild state of shock, even in
your mother tongue.
